PHP Refferer and Sessions

[nitestarz]

 I recently upgraded servers and the following code that worked on my old server with php 4x does not seem to work on the new server using 5x.
 
Basically it is an "Email a Friend" form that includes the referring url in the message. Everything else is fine except for this.

 

Any help would be appreciated. If you need any more info, let me know.

 

session_start();

if(!isset($_SESSION['referrer'])){
//get the referrer
if ($_SERVER['HTTP_REFERER']){
$referrer = $_SERVER['HTTP_REFERER'];
}
else{
$referrer = "http://www.domain.com";
}
//save it in a session
$_SESSION['referrer'] = $referrer; 
}

Sounds like the new server does not provide the HTTP_REFERER entry. 

 

You should not depend on this information anyway as some User-Agents do not provide it and it can be spoofed.

What do you recommend for another way?

Unfortunately that information is provided by the server so you would need to contact your hosting provider.

I do not know of another way to display that information.
